Abstract: A method of fabricating a wearable and elastically stretchable thermoelectric generator or other thermoelectric device can involve arranging thermoelectric pellets and printing a thermal insulation material alongside and/or around the thermoelectric pellets to form a core layer. The core layer can be cured, and a liquid metal can be selectively deposited on the thermoelectric pellets to form contact points. Printing conductive ink can form stretchable electrical interconnects that define connections among the thermoelectric pellets via the contact points to form an initial middle layer that includes the stretchable electrical interconnects. Printing a thermal interface material may form an initial outer layer positioned between the initial outer layer and an initial side of the core layer to form a layered assembly. The layered assembly may be inverted and receive additional printed layers building away from the core layer, such as an additional interconnect layer and an additional thermal interface layer.

Abstract: Present apparatuses, systems, and methods are directed to the conservation of energy expended to power devices, components, systems, etc., on an aircraft, and to power aircraft manufacturing components used in the manufacture of an aircraft in an aircraft manufacturing facility using a highly flexible thermoelectric composite device to generate electrical current by converting waste heat into electrical energy.

Abstract: Apparatuses, systems, and methods are directed for the use of at least one highly flexible thermoelectric device positioned in contact with and/or adjacent to heat-emitting aircraft assembly surfaces for the purpose of harvesting and/or converting energy in the form of heat to produce an electric current used to power an aircraft component.

Abstract: An example leadless pacemaker includes a housing including at least one outer surface and at least one energy storage device. The leadless pacemaker also includes at least one electrode coupled to the at least one energy storage device and configured to generate electrical pulses that are delivered to one or more chambers of the heat. The leadless pacemaker further includes at least one piezoelectric device disposed on at least a portion of the outer surface of the housing. The piezoelectric device is electrically coupled to the energy storage device. The piezoelectric device is configured to be generate electrical energy responsive to pressure changes in the heart.

Abstract: Method and system for forming of microcellular bubbles within a thermoplastic member employ an energy beam to form the microcellular bubbles within a selected portion of the thermoplastic member. A method includes infusing the thermoplastic member with a gas to form a gas-infused thermoplastic member and transmitting an energy beam onto the selected portion of the gas-infused thermoplastic member to induce subsurface heating of the selected portion of the gas-infused thermoplastic member to form microcellular bubbles within the selected portion of the gas-infused thermoplastic member.
